A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Phosphoric Acid (CAS 7664-38-2), also called orthophosphoric acid, is a mineral acid supplied in industrial and technical grades. Established uses include fertilizer and phosphate-salt manufacture, metal pickling, rust-proofing and brightening, water treatment, detergent production, food and beverage acidulation, and semiconductor etching.
Frequently Asked Questions
What is phosphoric acid mainly used for?
Phosphoric acid (CAS 7664-38-2) is a mineral acid used industrially in metal pickling, rust-proofing and brightening, as a feedstock for superphosphate fertilizers and phosphate salts, in water-treatment conditioning, detergent production, food and beverage acidulation, and as an etchant in semiconductor manufacturing. RawSource supplies it in industrial and technical grades.
Is phosphoric acid a strong or weak acid?
Phosphoric acid (H3PO4) is a triprotic mineral acid generally classified as a weak-to-moderate acid; it dissociates in three steps with decreasing strength. It is supplied as aqueous solution at various concentrations. Request a CoA for the exact assay of a given lot.
What is the chemical formula of phosphoric acid?
The formula is H3PO4 (also written H3O4P), also known as orthophosphoric acid. CAS number is 7664-38-2 and HS code 2809.20.
How is bulk phosphoric acid shipped and classified for transport?
Phosphoric acid solution ships under UN 1805 (Phosphoric acid, solution). RawSource supplies it in drums, IBC totes, and bulk; SDS and DOT documentation accompany each shipment. Confirm packaging and concentration with your sales rep when requesting a quote.
What is the cost of bulk phosphoric acid?
Bulk phosphoric acid pricing depends on grade, concentration, packaging, and volume. RawSource quotes drum, tote, and bulk loads to spec — request a current bulk quote with your target grade and quantity.
