AboutMethyl Orange

Methyl Orange (CAS 547-58-0) is an organic azo dye commonly utilized as a pH indicator. In its solid form, it appears as an orange-to-red crystalline powder, which dissolves in water to form a distinctively colored solution. Its primary utility stems from its sensitivity to hydrogen ion concentration, making it an essential tool for chemical analysis.

In the Indian industrial landscape, Methyl Orange is a staple in quality control laboratories across the pharmaceutical, textile, and water treatment sectors. It is frequently employed in volumetric analysis to determine the endpoint of titrations involving strong acids and weak bases. Furthermore, it serves as a specialized colorant in niche industrial applications where precise pH monitoring is critical for process stability.

For procurement in India, buyers should prioritize suppliers offering analytical grade certifications to ensure consistent transition intervals. It is recommended to source from reputable chemical distributors who provide COA (Certificate of Analysis) and MSDS documentation. Bulk procurement is typically handled in standardized glass or HDPE containers to prevent contamination and moisture absorption.
