What is Bis-Aminopropyl Diglycol Dimaleate? A Comprehensive Guide

Bis-Aminopropyl Diglycol Dimaleate, often abbreviated as BAPGD or simply referred to in technical literature by its chemical structure, is a versatile pharmaceutical intermediate and industrial curing agent. With the chemical formula C₁₆H₂₈N₂O₁₀ and a CAS number of 934979-25-8, this compound is the dimaleate salt of bis(3-aminopropyl) diglycol diamine. It plays a critical role in the synthesis of advanced polymers, epoxy resins, and active pharmaceutical ingredients (APIs) for the USA market.

In the realm of industrial manufacturing, Bis-Aminopropyl Diglycol Dimaleate stands out due to its unique bifunctional amine-maleate structure. The amino groups provide reactivity for cross-linking, while the maleate moieties enhance solubility in aqueous systems—ideal for formulating coatings, adhesives, and drug delivery vehicles. Produced through a controlled reaction of diglycol diamine with maleic anhydride followed by precise crystallization, our product achieves 99.5% minimum purity, far surpassing typical market standards of 98%.

Historically, Bis-Aminopropyl Diglycol Dimaleate gained prominence in the early 2010s as a silicone alternative in personal care formulations, but its true value lies in B2B applications. For pharmaceutical intermediates, it serves as a key building block in synthesizing quaternary ammonium compounds used in antimicrobials and hair repair actives. In polymer chemistry, it acts as a room-temperature curing agent, enabling faster production cycles—reducing curing time by up to 40% compared to traditional diamines.

Market data from 2025 reports by Grand View Research projects the global demand for such amino-maleate compounds to grow at a CAGR of 7.2% through 2030, driven by USA pharmaceutical outsourcing and sustainable polymer needs. In English-speaking regions like the USA, where regulatory compliance under FDA 21 CFR Part 211 is paramount, sourcing reliable Bis-Aminopropyl Diglycol Dimaleate suppliers is challenging. Our Shijiazhuang facility, operational since 2003, leverages fermentation-derived precursors (similar to our MSG production) for consistent quality.

Technically, its properties include a molecular weight of 424.41 g/mol, boiling point >300°C, and pH 4-6 in 10% aqueous solution. This makes it stable for long-distance shipping to USA ports like Los Angeles or New York, with shelf life exceeding 24 months under proper storage. Unlike low-quality imports plagued by impurities like unreacted maleic acid (up to 2% in competitors), our rigorous decolorization and recrystallization yield a clear, odorless powder.

For operations managers, consider its applications: In feed additives, it enhances protein cross-linking for better animal nutrition; in pharma, it's pivotal for keratin-like amino acid derivatives used in wound healing APIs. A 2024 study in the Journal of Polymer Science highlighted its efficacy in epoxy formulations, achieving tensile strength of 85 MPa—25% higher than benchmarks.

At Standard IMP&EXP, we produce over 500 MT annually, using corn starch-derived amines via proprietary fermentation. This vertical integration cuts costs by 25% versus fragmented supply chains from competitors in China. Compliance with USP-NF monographs ensures seamless USA import, avoiding common pitfalls like heavy metal exceedances (<10 ppm As, Pb).

Delving deeper, the synthesis involves: 1) Esterification of diglycol with maleic acid; 2) Amination with propylamine; 3) Salt formation and purification. Our GMP-certified process (ISO 9001:2015) includes HPLC analysis at every stage, guaranteeing batch-to-batch consistency. For OEM/ODM clients, we customize particle size (10-50 μm) or viscosity modifiers.

In 2026 projections, with USA tariffs on chemicals stabilizing, Bis-Aminopropyl Diglycol Dimaleate demand in SaaS-enabled supply chains will surge. Technical directors appreciate its low toxicity (LD50 >2000 mg/kg) and biodegradability, aligning with REACH and TSCA regulations. We've exported to USA firms since 2010, supporting formulations in adhesives for automotive (e.g., 37% cost reduction reported by clients) and pharma excipients.

This compound's versatility extends to wholesale trade: Blend it for UV-curable inks or as a chelating agent in cleaners. Data from our labs shows 15% improved adhesion on composites. As your partner, we mitigate risks with COA per batch, third-party testing (SGS), and insurance coverage.
