What is 3-Methyl-2-benzothiazolinone hydrazone hydrochloride monohydrate CAS 38894-11-0?

3-Methyl-2-benzothiazolinone hydrazone hydrochloride monohydrate is a reagent for the photometric determination of aliphaticaldehydes. Determination of hexose chemical booksamines in glycosaminoglycans and photometric determination of trace selenium in environmental samples. Formaldehyde in the air reacts with phenol reagent to form azine, which is oxidized by ferric ions in acidic solution to form a blue-green compound. The quantity is determined by color comparison based on the depth of the color.

Application

1. Environmental testing: 3-Methyl-2-benzothiazolinone hydrazone hydrochloride monohydrate is used in the MBTH method to detect formaldehyde in the air. Formaldehyde in the air reacts with phenol reagent to form azine. Azine is oxidized by ferric ions in an acidic solution to form a blue-green compound. The concentration of formaldehyde is quantitatively determined by colorimetry based on the depth of the color. The national standard GB/T16057-95 quantitatively detects the content of formaldehyde by reacting an excess of 3-methyl-2-benzothiazole hydrazone hydrochloride monohydrate with formaldehyde. It is suitable for determining the content of formaldehyde in the air of workshops and can also be used for the detection of trace amounts of formaldehyde.

2.Biochemical: As a reagent for photometric determination of aliphatic aldehydes, it reacts with aliphatic aldehydes to form purple hydrazone compounds. Further, its absorbance is measured by photometry to obtain the concentration of aliphatic aldehydes. It can also be used to determine hexosamine in mucopolysaccharides and for photometric determination of trace selenium in environmental samples.
