General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Measurement of urinary methoxyphenols and their use for biological monitoring of wood smoke exposure.[Pubmed: 11161664]

Environ Res. 2001 Feb;85(2):145-58.

A urinary assay for methoxyphenols was developed for the biological monitoring of wood smoke exposure.
METHODS AND RESULTS:
Methoxyphenols in 10-ml samples of urine were extracted after acid hydrolysis using XAD in a solid-phase extraction cartridge. The methoxyphenols were eluted with ethyl acetate and then analyzed by gas chromatography/mass spectrometry. Specific chemicals quantified were guaiacol, 4-methylguaiacol, 4-ethylguaiacol, 4-propylguaiacol, syringol, 4-methylsyringol, 4-Ethylsyringol, vanillin, eugenol, and syringaldehyde. Recoveries ranged from 60 to 90%, with coefficients of variation of < or =20%. Background levels of the compounds were measured in 21 nonsmoking adults. Guaiacol, 4-methylguaiacol, eugenol, and vanillin were detected in all subjects. An experimental feeding of a commercial wood smoke flavoring demonstrated that methoxyphenols were rapidly and efficiently eliminated in urine.
CONCLUSIONS:
Preliminary field studies demonstrated that urinary excretion rates of some methoxyphenols increased after inhalation exposure to wood smoke.

Determination of Eucalyptus spp lignin S/G ratio: a comparison between methods.[Pubmed: 20133130]


METHODS AND RESULTS:
The syringyl/guaiacyl ratio was determined for six different Eucalyptus spp. wood clones cultivated in four regions in Brazil. The determinants were made by pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and the results were compared with those obtained by alkaline nitrobenzene oxidation method. The S/G ratios were obtained considering all the identified lignin derivatives in the pyrograms and also using two groups of markers. The first group of markers consisted of guaiacol, 4-methylguaiacol, 4-vinylguaiacol, trans-isoeugenol, syringol, 4-methylsyringol, 4-vinylsyringol and trans-4-propenylsyringol compounds as markers. The second group included guaiacol, 4-methylguaiacol, 4-vinylguaiacol, vanillin, 4-Ethylsyringol, 4-vinylsyringol, syringaldehyde, syringylacetone and trans-4-propenylsyringol.
CONCLUSIONS:
It was observed from the statistical analysis that the values of S/G obtained by Py-GC-MS using the two groups of markers did not differ significantly from those obtained by nitrobenzene oxidation method.
