Hydrochloric Acid – Reagent Grade (AR/GR) & Electronic Grade (HCl) 31%-36%

High-purity Hydrochloric Acid comes in two distinct categories for different technical settings. Reagent Grade (AR and GR) supports laboratory work – titrations, pH adjustments, and metal digestions where consistent purity determines analytical accuracy. Electronic Grade serves semiconductor and electronics manufacturing – wafer cleaning, oxide removal, and component processing where trace contamination directly affects product yields.

Industrial hydrochloric acid cannot substitute for these grades. Labs and fabs require certified purity documentation that bulk shipments do not provide. AR meets analytical reagent standards. GR offers tighter impurity control. Electronic Grade removes metals and particles to levels suitable for sensitive electronics applications.

Typical specification: 31% – 36% HCl. Each grade ships with a lot-specific Certificate of Analysis.

Grades Available: AR | GR | Electronic Grade

Certified Purity, Fully Traceable – Every container includes a COA documenting actual metal content and impurity levels. You receive verified data for your quality records.

Three Grades for Different Applications – AR for routine lab titrations and digestions. GR for stricter analytical requirements. Electronic Grade for semiconductor and electronics manufacturing.

Lab-Ready Packaging – Supplied in 500mL, 1L, 2.5L, 5L bottles, and 20L carboys. No need to handle heavy industrial drums.

Export Track Record – 13 years in chemical exports. Complete documentation supports your quality system.

Acid-Base Titrations and pH Work – QC laboratories use reagent hydrochloric acid for alkalinity titrations, buffer preparation, and various volumetric analyses. The acid must deliver consistent concentration without interfering impurities. Our AR grade provides the reliability that routine analytical work requires.

Metal Sample Digestion – Metals and alloys require acid digestion before elemental analysis by ICP or AAS. Reagent hydrochloric acid dissolves many metals and is often mixed with nitric acid (aqua regia) for refractory materials like gold and platinum. Our GR grade offers lower impurity backgrounds for trace metal work.

Electronics Component Cleaning – Electronic Grade Hydrochloric Acid removes metal oxides and ionic contaminants from semiconductor wafers, lead frames, and circuit boards. The purity level ensures no residue remains that could affect device performance or subsequent bonding operations.

Wafer Cleaning (Semiconductor Manufacturing) – In semiconductor fabs, electronic grade hydrochloric acid is a component of standard cleaning solutions (SC-2) used to remove metal contamination from silicon wafers. Acid purity directly affects cleaning effectiveness and device yields.

pH Adjustment in Laboratory Settings – Research and QC labs use reagent hydrochloric acid for precise pH adjustment of buffers, mobile phases, and reaction mixtures. The consistent strength allows reproducible results across different batches.

Pharmaceutical Quality Control – QC labs test raw materials and finished drug products. Reagent hydrochloric acid prepares samples for compendial tests (USP, EP) and instrumental analysis. Batch-specific documentation supports regulatory inspections.

Nitric Acid (HNO₃), AR/GR Grade – Mixed with hydrochloric acid to form aqua regia for dissolving noble metals; analytical labs often purchase both

Sulfuric Acid (H₂SO₄), AR/GR Grade – Used alongside hydrochloric acid for various wet chemistry applications

Hydrogen Peroxide (H₂O₂), Electronic Grade – Combined with hydrochloric acid in certain semiconductor cleaning formulations

Note: Reagent and electronic grades differ fundamentally from industrial acid. Never substitute industrial grade in analytical or semiconductor work – contamination will compromise results.

Important – Corrosive – Fume Hood Required

High-purity hydrochloric acid releases irritating vapors. Use in fume hoods. Wear appropriate PPE including gloves and goggles. Segregate from alkalis and oxidizers. Store in original containers away from incompatible materials. Contact us for SDS.
