Formic Acid – Reagent Grade (AR/GR) & Electronic Grade (HCOOH) 85%-98%

Formic Acid – the simplest carboxylic acid – appears in high-purity forms for specialized applications. Reagent Grade (AR and GR) serves analytical laboratories where consistent purity drives accurate measurements. Electronic Grade serves semiconductor and electronics manufacturing where trace contamination cannot be tolerated.

Unlike acetic or other organic acids, formic acid offers stronger acidity combined with reducing properties. This dual nature makes it valuable for applications where both functions matter. AR meets analytical reagent standards. GR offers tighter impurity control. Electronic Grade removes metals and particles to levels suitable for sensitive electronics work.

Typical specification: 85% – 98% HCOOH. 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. No guesswork – you receive verified data.

Three Grades for Different Needs – AR for routine laboratory work. 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. Small volumes prevent waste and contamination.

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

pH Calibration and Buffer Preparation – Analytical laboratories use reagent formic acid to prepare pH calibration standards and buffer solutions. Its predictable dissociation behavior makes it suitable for certain low-pH applications where mineral acids may introduce unwanted ions.

Metal Surface Cleaning (Electronic Grade) – Electronic Grade Formic Acid removes oxide layers from metal surfaces without aggressive etching. It is used in electronics manufacturing for cleaning solder pads, lead frames, and connector contacts. The organic nature leaves no corrosive chloride residues that could cause long-term reliability issues.

Sample Preparation for Analysis – Reagent formic acid serves as a solvent or digestion aid for certain organic samples before chromatographic or spectroscopic analysis. It also acts as a mobile phase additive in liquid chromatography (LC-MS) to improve peak shape and ionization efficiency.

Semiconductor Wafer Processing – In semiconductor manufacturing, electronic grade formic acid is used for certain cleaning and residue removal steps. Its reducing properties help remove metal oxides from wafer surfaces. The high purity ensures no particle or metal contamination remains.

Polymer and Material Testing – Quality control labs use reagent formic acid to dissolve certain polymers for viscosity or molecular weight testing. Nylon and polyamide samples often require formic acid as the dissolution solvent.

Pharmaceutical Quality Control – QC laboratories test raw materials using reagent formic acid as a solvent or mobile phase additive. Batch-specific documentation supports regulatory compliance.

Acetic Acid (CH₃COOH), AR/GR Grade – Another organic acid for laboratory use; analytical labs may stock both for different applications

Oxalic Acid (H₂C₂O₄), AR/GR Grade – Used alongside formic acid for certain metal cleaning and analytical procedures

Methanol (CH₃OH), AR/GR Grade – Often paired with formic acid as a mobile phase component in LC-MS analysis

Note: Reagent and electronic grades differ from technical grade. Never substitute technical grade in analytical or semiconductor work – purity will not meet requirements.

Important – Corrosive – Fume Hood Required

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