CAS 16940-66-2 CAS No. 16940-66-2 Chemical Name: Sodium borohydride borohydride has a strong selective reduction, being able to selectively reduce a carbonyl group is to a hydroxyl group without reacting with the carbon-carbon double bond and triple bond reaction. A small amount of sodium borohydride can restore the nitrile to the aldehyde with the excess amount being reduced to the amine. Uses Sodium borohydride (NaBH4) is a versatile reducing agent used in a number of industrial processes. Major applications include organic and pharmaceutical synthesis, wastewater treatment, and paper pulp bleaching. Sodium borohydride plays such a significant role in organic synthesis. It is a good reducing agent which has stable performance and selective reduction. It can be used as the reducing agents of aldehydes, ketones and acid chlorides; also as foaming agent for plastic materials, hydrogenating agent of making dihydrostreptomycin, intermediate of making potassium borohydride, raw materials in synthesizing borane, as well as the treatment agent of paper industry and mercury-containing waste water. Sodium borohydride provides organic chemists a very convenient and mild means for reduction of aldehydes and ketones. Before this, people usually use metal/alcohol approach to reduce carbonyl compound. Sodium Releases hydrogen to blow in material.

Aroma and flavour The odour and flavour of cumin is derived largely from the essential oil, which contains cumaldehyde or cuminic aldehyde as the main constituent. Other ingredients of the oil are dihydrocuminaldehyde, dl-pinene, dâ??pinene, para-cymene, dipentene, and cuminyl alcohol. Synthetic cuminaldehyde is an adulterant to cumin oil and is very difficult to detect chemically. The dried seed of cumin has 2.5 to 5 percent essential oil on a dry weight basis and is obtained by steam distillation. Cumin is the dried, white fruit with greyish brown colour of a small slender annual herb. The surface of the fruit has 5 primary ridges, alternatively has 4 less distinct secondary ridges bearing numerous short hairs. The plant is 15 to 50 cm high. The aromatic seed like fruit is elongated, ovoid, 3 to 6 mm long, slightly bitter and has a warm flavour. The flowers are white or rose coloured in small umbels.
