Maltose Specification

The Maltose, with the CAS registry number 69-79-4, is also known as Sunmalt. It belongs to the product categories of Disaccharide Molecular Biology; Biochemicals and Reagents; BioUltra Biochemicals and Reagents; BioUltraMolecular Biology; Carbohydrates; DNA & RNA Purification; Molecular Biology Reagents; Reagents. Its EINECS number is 200-716-5. This chemical's molecular formula is C12H22O11 and molecular weight is 342.30. What's more, its systematic name is 4-O-α-D-Glucopyranosyl-β-D-glucopyranose. Its classification codes are: (1)Drug / Therapeutic Agent; (2)Flavoring Agents; (3)Food Additives; (4)Human Data; (5)Natural Product; (6)Reproductive Effect; (7)Sweetening Agents; (8)Tumor data. This chemical is the second member of an important biochemical series of glucose chains. Maltose is the disaccharide produced when amylase breaks down starch. It is found in germinating seeds such as barley as they break down their starch stores to use for food. It is also produced when glucose is caramelized. This substance has the ability to reduce the Fehling’s solution, due to its free aldehyde. 

Physical properties of Maltose are: (1)ACD/LogP: 2.838; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 2.78; (4)ACD/LogD (pH 7.4): 1.65; (5)ACD/BCF (pH 5.5): 74.05; (6)ACD/BCF (pH 7.4): 5.45; (7)ACD/KOC (pH 5.5): 730.25; (8)ACD/KOC (pH 7.4): 53.76; (9)#H bond acceptors: 6; (10)#H bond donors: 3; (11)#Freely Rotating Bonds: 5; (12)Polar Surface Area: 96.22 Å2; (13)Index of Refraction: 1.697; (14)Molar Refractivity: 76.53 cm3; (15)Molar Volume: 198.565 cm3; (16)Polarizability: 30.339×10-24cm3; (17)Surface Tension: 72.8 dyne/cm; (18)Density: 1.512 g/cm3; (19)Flash Point: 230.135 °C; (20)Enthalpy of Vaporization: 92.805 kJ/mol; (21)Boiling Point: 601.506 °C at 760 mmHg; (22)Vapour Pressure: 0 mmHg at 25°C.

When you are using this chemical, please be cautious about it as the following:
This chemical is harmful if swallowed. It is irritating to eyes, respiratory system and skin. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. When using it,
you need wear suitable protective clothing.
