o-Toluic Acid CAS 118-90-1

What o-Toluic Acid Is

o-Toluic acid (C₈H₈O₂) is benzoic acid with a methyl group beside the carboxyl group, sold as white crystals or flakes. It is the ortho isomer of the three toluic acids; meta and para carry separate CAS numbers, so quote the CAS when ordering. Most routes first turn it into an acid chloride, ester or amide. UATChem supplies industrial and pharmaceutical grades, with assay on the COA.

Agrochemical, Pharmaceutical and Dye Intermediate Uses

• Agrochemicals. A starting aromatic acid for active ingredient and intermediate synthesis in crop protection routes.
• Pharmaceuticals. Built into amide and ester derivatives and active pharmaceutical ingredient pathways.
• Dyes and pigments. An intermediate for organic pigments and aromatic colorants used in textiles and plastics.
• Other routes. Converted to its acid chloride, ester or amide for initiators, fragrance and specialty derivatives.

Typical Specifications

Industrial and pharmaceutical grades differ in assay, isomer distribution, moisture and particle form, reported on the COA for each lot; the table below identifies the material.

Packaging, Documents and Ordering

• Packed in 25 kg paper bags and fibre drums, with 1000 kg jumbo bags for volume orders; keep packs sealed, cool, dry and dark, away from strong bases and oxidizers.
• Industrial and pharmaceutical grades are available, and every lot ships with COA, TDS and SDS covering assay, isomer and impurity detail; samples and trial orders are supported.
• For a quote, UATChem needs the CAS, grade, quantity, packing and destination port.

FAQ

Q: Is o-toluic acid the same as meta or para toluic acid?

A: No. The isomers have separate CAS numbers and melting points; o-toluic acid is 118-90-1, so quote the CAS, not just the name.

Q: Can o-toluic acid be used directly in water based processes?

A: It barely dissolves in cold water, so run it in organic solvents or convert it to the acid chloride or ester before use.

Q: What grade and packing does UATChem offer for o-toluic acid?

A: Industrial and pharmaceutical grades come in 25 kg paper bags, fibre drums and jumbo bags; assay and isomers are on the COA.
