Acid Blue 145 Shortages

Are you having a hard time finding Acid Blue 145 (CAS 6408-80-6)?  You are not alone.  The worldwide dye and colorant market has been heavily impacted by supply shortages stemming from stricter environmental and regulatory controls implemented by both the Chinese and Indian governments over the past few years.  Additional challenges include recent industrial explosions and factory shutdowns throughout China.

How Are Regulatory Measures Are Restricting Acid Blue 145 Production?

Historically, Acid Blue 145 has been manufactured by a very small number of manufacturers and the vast majority of this dye has been made in China. However, within recent years, China’s anti-pollution clampdown with regards to its new environmental enforcement regime has forced the closure or reduced the production output of many of its dye factories. Many of those that are still running were also severely hit with restrictions in the supply of key dye ingredients. According to, this resulted in price hikes among several well-known dyes.

Ultimately, these environmental and regulatory measures eventually brought the manufacturing of Acid Blue 145 to a halt.  It is not known when manufacturing of this dye will resume, if ever.
