Description
TOLUALDEHYDES, also known as toluic aldehydes, are organic compounds that consist of a group of aldehydes derived from toluene. They are colorless liquids with a sweet and herbaceous odor, reminiscent of bitter almonds. TOLUALDEHYDES are slightly soluble in water but soluble in alcohol and ether. They are combustible and exist in ortho, meta, and para isomers.
Uses
Used in Perfumery Industry:
TOLUALDEHYDES are used as fragrance components in the perfumery industry due to their sweet and herbaceous odor, which adds a pleasant scent to various perfumes and colognes.
Used in Pharmaceutical Industry:
TOLUALDEHYDES serve as intermediates in the synthesis of various pharmaceutical products, contributing to the development of new drugs and medications.
Used in Flavoring Industry:
TOLUALDEHYDES are used as flavoring agents, providing a cherry pit, coumarin, almond, and sweet taste with a slight powdery hay and vanilla-like nuance to different food and beverage products.
Used in Dyestuff Industry:
TOLUALDEHYDES are utilized as intermediates in the production of dyes, playing a crucial role in the development of various colorants for the textile and other industries.
Taste Threshold Values:
TOLUALDEHYDES have taste threshold values at 15 ppm, characterized by a cherry pit, coumarin, almond, sweet, with a slight powdery hay, and vanilla-like nuance.
Occurrence:
TOLUALDEHYDES are naturally found in various food items such as roasted nuts, tomato, cooked beef, beef fat, cider, coffee, tea, and elderberry juice, contributing to their unique flavors and aromas.
Preparation
By oxidation of o-, m-, or p-xylene (chemical or electrolytical oxidation).
Metabolism
Aromatic aldehydes are oxidized in vivo almost entirely to the corresponding acid. Thus, in rabbits, p-tolualdehyde is converted to p-toluic acid which has been detected in the urine as the ester glucuronide (Williams, 1959). p-Tolualdehyde was oxidized to p-toluic acid by resting cells of Pseudomonas aeruginosa (Omori & Yamada, 1970). Perillaldehyde dehydrogenase, isolated from a soil pseudomonad, catalysed the oxidation of m- and p-tolualdehyde but not of o-tolualdehyde (Ballal, Bhattacharyya & Rangachari, 1967). The reduction of p-tolualdehyde by NADH was catalysed by horse-liver alcohol dehydrogenase (Blomquist, 1966) and by yeast alcohol dehydrogenase at pH 8.5-9.5 (Klinman, 1975). A non-specific NADPH-linked aldehyde reductase isolated from various areas of bovine brain also catalysed the reduction of p-tolualdehyde (Tabakoff & Erwin, 1970).
Check Digit Verification of cas no
The CAS Registry Mumber 1334-78-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,3 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1334-78:
(6*1)+(5*3)+(4*3)+(3*4)+(2*7)+(1*8)=67
67 % 10 = 7
So 1334-78-7 is a valid CAS Registry Number.
