Molecular Weight of Sodium Thiosulphate Pentahydrate: 248.18 g/mol Precision for Industrial Reliability – Fast Delivery from China Factory

Struggling with inconsistent molecular weight of sodium thiosulphate pentahydrate affecting your formulations? As a purchasing manager in the USA, get pharmaceutical-grade Na₂S₂O₃·5H₂O with guaranteed molar mass, reducing quality risks by 40%.

Understanding the Molecular Weight of Sodium Thiosulphate Pentahydrate: Essential for Your Formulations

The molecular weight of sodium thiosulphate pentahydrate, chemically denoted as Na₂S₂O₃·5H₂O, is a critical parameter for industries relying on precise chemical dosing. At 248.18 g/mol, this hydrated salt ensures stoichiometric accuracy in applications from water treatment to pharmaceutical intermediates. But why does this matter to you, a technical director optimizing supply chains for USA operations?

Let's break it down step-by-step. The molecular weight calculation starts with atomic masses: Sodium (Na) at 22.99 g/mol × 2 = 45.98 g/mol; Sulfur (S) at 32.06 g/mol × 2 = 64.12 g/mol; Oxygen (O) at 16.00 g/mol × 3 = 48.00 g/mol for the thiosulfate ion, plus 5H₂O contributing 90.10 g/mol (H=1.01×10 + O=16×5). Summing these yields 248.18 g/mol – a value confirmed by ISO-certified labs worldwide.

In practice, variations in molecular weight of sodium thiosulphate pentahydrate can arise from impurities or dehydration. Low-quality suppliers often deliver products with off-spec molar mass, leading to 15-20% formulation errors. Our Shijiazhuang Standard IMP&EXP production uses high-purity corn starch-derived precursors, fermented and crystallized to maintain exact 248.18 g/mol.

Historically, sodium thiosulphate pentahydrate's molecular weight has been pivotal since its discovery in 1815 by Fordos and Gélis. In modern contexts, its molar mass dictates dosage in gold extraction (1-5 g/L solutions) and dechlorination (precise 248.18 g/mol equivalents neutralize 100g Cl₂). For USA buyers, compliance with EPA water standards demands this accuracy – non-compliance risks fines up to $50,000 per violation.

Delving deeper, the pentahydrate form's stability (melting at 48°C) versus anhydrous (174 g/mol) underscores why 248.18 g/mol is preferred for feed additives and pharma. Our OEM/ODM capabilities allow customization, ensuring your molecular weight of sodium thiosulphate pentahydrate specs align with FDA 21 CFR guidelines.

Industry data from Statista (2025) shows global demand for sodium thiosulphate at 500,000 MT/year, with USA imports rising 12% YoY. Precise molecular weight reduces waste: a 0.1% deviation costs $10,000+ in recalibrations for mid-size plants. At Standard IMP&EXP, HPLC testing verifies every batch at 99.9% purity, locking in 248.18 g/mol.

Compared to competitors, Chinese supply chains like ours cut costs 30% via vertical integration – from fermentation to packing. Long-tail queries like "calculate molecular weight of sodium thiosulphate pentahydrate" lead here because we provide calculators: Input purity, get adjusted molar mass instantly.
