Applications & Use Cases
- ▸ Synthesis intermediate for acetylsalicylic acid (aspirin), salicylate esters, and a range of fine-chemical and dye-stuff derivatives.
- ▸ Cosmetic-grade beta hydroxy acid (BHA) used in acne, exfoliating, and anti-dandruff personal-care formulations for keratolytic and pH-adjustment functions.
- ▸ Rubber-compounding retarder (historically marketed as Retarder W) that controls premature scorch during vulcanization.
- ▸ Chemical intermediate in the manufacture of azo and triphenylmethane dyes, pigments, and color lakes for coatings and inks.
- ▸ Preservative and pH-control additive in industrial and household formulations where its antimicrobial and acidifying action is required.
